掠海飞行导弹击水概率的仿真研究

本文对掠海导弹的击水概率问题进行了研究,提出了用均匀设计、Monte—Carlo法和逐步回归法建立击水概率预报公式的仿真方法,并结合某型号的反舰导弹进行计算,得到了满意的结果。本文还利用表观频率和表观频谱的概念,建立起飞航导弹的背景干扰——海浪和阵风的数学模型,并用波叠加法进行了数字仿真。

SIMULATION STUDY OF DITCHING PROBABILITY OF SEA SKIMMING FLYING VEHICLE

Sea skimming flight has been widely used and proved to be an effective penetration tactics during the recent years for most vehicles. The study detailed herein deals with the ditching probability (DP) of sea skimming flying vehicle. A simulation approach to obtain the prediction formula for DP has been given using the uniform experimental design method, the Monte-Carlo method and the regressive interpolation method. By using the approach, the simulations of DP for a given anti-ship missile have been carried out, and the results are satisfactory. Furthermore, the mathematical models of sea wave and gust wind have been built using.the concept of apparent frequency and spectrum, and they are simulated by means of subwave superposition method.
